lsst.meas.astrom.MatchTolerancePessimistic(maxMatchDist=None, autoMaxMatchDist=None, maxShift=None, lastMatchedPattern=None, failedPatternList=None)¶ Bases:
lsst.meas.astrom.MatchToleranceStores match tolerances for use in AstrometryTask and later iterations of the matcher.
MatchPessimisticBTask relies on several state variables to be preserved over different iterations in the AstrometryTask.matchAndFitWcs loop of AstrometryTask.
Parameters: - maxMatchDist :
lsst.geom.Angle Maximum distance to consider a match from the previous match/fit iteration.
- autoMaxMatchDist :
lsst.geom.Angle Automated estimation of the maxMatchDist from the sky statistics of the source and reference catalogs.
- maxShift :
lsst.geom.Angle Maximum shift found in the previous match/fit cycle.
- lastMatchedPattern :
int Index of the last source pattern that was matched into the reference data.
- failedPatternList :
listofint Previous matches were found to be false positives.
- maxMatchDist :
